Staying warm is the key feature of the Men’s Aspire Thermal Wetsuit. The Aspire Wetsuit is crafted with Premium SCS Yamamoto fabrics known for their high heat retention with a Heat-Tech fleece lining for the key muscles groups which require extra warmth when swimming in colder conditions. Fast both in and out of the water, the aqua dynamic 'SCS' Nano coating reduces the drag of a regular swimmer, while the Pro Speed CuffsTM on the arms and the legs help with getting the suit off quickly so you’re ready to jump into a warm shower.Chest, leg and body panels are a combination of 3mm, 4mm and 5mm thickness plus a 4mm lining, but the shoulders and arms still maintain a 2mm thickness with high stretch lining for flexibility. The suit is suitable for anybody swimming in waters between 10-18 Celsius.
